Always return after starting server in cli/run.py

[federicotdn]

Proposed changes:

• Add return statements in cli/run.py::run() so that the function always returns after the server has finished running. Fixes "No model found" error message when model was loaded correctly #4012.

Status (please check what you already did):

• made PR ready for code review
• added some tests for the functionality
• updated the documentation
• updated the changelog
• reformat files using black (please check Readme for instructions)

Hi,

Inspite of putting return statement after every rasa.run command, I am getting the error 'No model found'.
Is it a change in the new version because in the older version, there was no such problem.

@kshitiz1318 The commit I pushed to master should have solved the issue, it will be part of the next release. What's the exact command you're running to get the error?

[kshitiz1318]

Now I used your rasa/cli/run.py file, there is no error. But when I send any message in the rasa shell it exits the shell without responding anything.
Command which I was and I am using is either rasa shell or rasa run. Earlier there was error, now there is no error but it is not running

There's a chance that changing only the run.py file won't solve the problem (if you're using the latest stable release), because there have been changes to other files as well. Could you try cloning the repo and trying again with the latest commit?

Sure will try that and let you know.
